Ant keeps running and data analysis doesn't end

[zteuber]

Dear Anthony,

I'm running a 3-factor model using the "antcolony.mplus" function. Below is my R script. However, it keeps calculating, and after 2 days, it still hasn't finished (see screenshot). Are there any errors in my R script? I've also attached my data.

Best regards, Ziwen

initial.MplusAutomation.model <- MplusAutomation::mplusObject( TITLE = "PGrit Shortform 3 factors;", MODEL = "PE BY PG_PGPE2 PG_PGPE3 PG_PGPE5 PG_PGPE7; SP BY PG_PGSP2 PG_PGSP4 PG_PGSP5 PG_PGSP6 PG_PGSP7; AG BY PG_PGAG1 PG_PGAG2 PG_PGAG3 PG_PGAG4 PG_PGAG6 PG_PGAG7;", ANALYSIS = "ESTIMATOR = WLSMV;", VARIABLE = "CATEGORICAL = PG_PGPE2 PG_PGPE3 PG_PGPE5 PG_PGPE7 PG_PGSP2 PG_PGSP4 PG_PGSP5 PG_PGSP6 PG_PGSP7 PG_PGAG1 PG_PGAG2 PG_PGAG3 PG_PGAG4
PG_PGAG6 PG_PGAG7;", OUTPUT = "stdyx;", rdata = data)

finally, call the function with some minor changes to the default values.

Pgritshort = antcolony.mplus(ants = 20, evaporation = 0.7,

mplus = initial.MplusAutomation.model,
list.items = list(c("PG_PGPE2","PG_PGPE3","PG_PGPE5","PG_PGPE7"), 
                  c("PG_PGSP2","PG_PGSP4","PG_PGSP5","PG_PGSP6","PG_PGSP7"), 
                  c("PG_PGAG1","PG_PGAG2","PG_PGAG3","PG_PGAG4","PG_PGAG6","PG_PGAG7")), 
full = 15,
i.per.f = c(4,4,4), factors = c('PE','SP','AG'), 
steps = 3, max.run = 50, resultfile = NULL,
summaryfile = 'summary.txt',
min.CFI = 0.95, min.TLI = 0.95, max.RMSEA = 0.08,
feedbackfile = 'iteration.html', Mplus.Automation=TRUE,
dataOut = '3factorModel.dat',
modelOut = '3factorModel.inp')

Hello,

Unfortunately, the MPlus portion of the code is quite old and I do not have an installation of MPlus that I can test it with. The only thing I can suggest at the moment is to try the lavaan version of the function and see if you have any difficulties that way.

Hello,

I tried the lavaan version. Unfortunately, it didn't work. Below you can see my codes and a screenshot of the error.

Best wishes, Ziwen
